This is just a standard still life of mustard squirted all over a pair of glasses. Pretty common stuff. The point is to show how just a small change in lighting can make such a difference. The shot on the left was made with a single studio strobe, low and to the left, with a snoot on it, which produced a hard, angular, almost painfully contrasty image. The shot on the right was made with the same strobe, directly overhead, using a big softbox creating a soft, nearly shadowless image. I find light endlessly fascinating.
Here’s the big flickr version.
